Patented July 2d, 1923.
MAX L. HILLMER, or nnrnorr, MICHIGAN, Assicnon TO THE REMY ELEo'rnIc COMPANY, n CORPORATION or INDIANA.
COVER AND COVER-SECURING MEANS.
Application filed October 30, 1918. Serial No. 260,243.
To all whom it may concern:
Be it known that I, MAX L. HILLMER, a citizen of the United States of America, residing at Detroit, county of Wayne, State of Michigan, have invented certain new and useful Improvements in Cover and Cover Securing Means, of which the following is a full, clear, and exact description.
This invention relates to covers and cover securing means for apparatus, as such for example, ignition coils for automobiles, which when in use are subjected to jarring and vibration; and to devices for securing the covers in position in such a manner that they cannot become loose during jarring or vibration, said devices permitting the removal ofthe cover when desired.
The chief object of this invention is to provide improved means for securing the covers of an apparatus in position in the will be held in position in a thoroughly reliable manner, but so that the covers can be readily removed when desired.
Other and further objects of this invention will be apparent from the following description, reference being had to the acconipanying drawings, wherein a preferred embodiment of the present invention 1s clearly shown.
Referring to the drawings:
, Fig. 1 is a side elevation of an ignition coil to which the present invention is applied, the cover being shown in section for sake of clearness; V
Fig. 2 is a plan view of the cover shown in Fig. 1;
Fig. 3 is a fragmentary section on the line 38 of Fig.2;
Fig. 4 is a side elevation ofthe nut form -v ing part of the securing device; 7 1
Fig. 5 is a bottom plan view thereof; and Fig. 6 is view of a modified form of the invention.
Referring to the drawings, 20 indicate as a whole an ignition coil which maycomprise a cylindrical portion 21-, a bottom 22 and a top 23 serving as a cover support, within which the windings and condenser of the coil may be enclosed. A rod 24 having threaded'engagement at its lower end. with the bottom 22 extends upwardly through the top 23 and has at its upper end a threaded portion 25.- A nut 26 cooperates with the threaded portion 25 and serves togsecure the parts 21, 22 and'23 in position, in order to form a hollow compartment for certain parts of the ignition coil. sistance element 27 is mounted upon the top 23. The ignition coil may have a number of The ignition coil reterminals which are mounted upon the cover 23, one of these terminals being shown at'28'.
It may be desirable to cover or to en close the resistance element and the -terminals, in order to protect them from dust and dirt or grease, particularly where the ignition coil is usedvon an automobile. In
a order to provide such an inclosure I provide a cover which cooperates with the top member 23 to form an enclosure for the re- 7 sistance element 27 andthe terminal 28. In manner referred to, that is, so that the covers order to provide'a means for securing the cover in position upon the top member 23 of the ignition coil, I take advantage of the presence of the rod 24, and extend the rod beyond the nut'26 so that the rod 24: may pass through an aperture 31 formed in the cover 30. The nut 32 cooperateswith the 1 nut with a lock washer in order to prevent the nut from turning due 'to jarring or.
vibration. But in the present invention I- have eliminated the lock washer and have provided cooperating portions or surfaces.
on the cover and the nut in order to prevent the nut from turning, except where it I is desired to remove the. cover.
' The cooperating portionsreferred to con cover by extruding themetal of the cover sist of grooves 33 formed on the under sur- 7 face of the nut as shown more clearly in Figs. 4 and 5;'and ridges 34. areprovided in the in the manner shown in Fig. 3. These ridges 34: bear the same relation to the aperture 31 as the grooves 33 bear to the nut 32.
It is apparent, therefore that in order to the tapped holein secure the cover in position it. is'nec'essary only, first to place the cover upon the top 23 with he rod 2 extending through the aperture 31 of the cover, and then to place the nut 32 on the threaded portion 25 with the grooved surface and adjacent the cover. The nut is then screwed downwardly until the lower surface thereof contacts with the ridges 84. The nut is screwed down further on the rod 24; causing the cover to downwardly as viewed in Fig. 1, but when the grooves 33 and the nut 82 come opposite the ridges 3d, the ridgesfi l will spring;- upwardly as viewed in Fig. 1, into engagement with the grooves 33 thus locking the nut in position. The more the nut is screwed downwardly on the rod E i the more lirr; will be the locking engagement between the ridges 34s and the grooves 33. Thus will be seen that the lock washer which is usually employed has been eliminated. I have taken advantage of the flexibility of the cover as a means which will yieldingly but securely hold the nut in position and keep it from turning when the coil is being subjected to jarring or vibration. Now when it is desired to remove the cover it is only necessary to apply a wrench or similar device to the nut to remove the same from the rod 25. When this has been done the cover can be removed simply by lifting it away from the coil 20.
If desired, the cover may be provided with the depressions 33, and the nut may be provided with the ridges 34.
Where the rod 24 is not long enough to extend through the cover, the nut 40 shown in Fig. 6 may be used. This nut 40 has a shank portion d1 which extends through the aperture 34: in cover 30, and is provided with a tapped hole 42 which is engaged by the screw-threaded end 25 of the rod 24.
The nut a0 is provided with grooves 48 which cooperate with the ridges 3a in the manner described in connection with the first form of the invention. A split ring as cooperates with a groove on the shank 41 to prevent accidental withdrawal of the nut from the cover.
By referring to Fig. 1, it will be noted that the cover and supporting member 23 have annular coopera'tingsurfaces, whereby, when pressure is applied by the locki nut, the cover will be prevented from turning with respect to the member 23 by virtue of the frictional force between these co-opcrating surfaces.
While the cover and securing device has been shown in connection'with ignition coil it is to be understood that the invention could be applied to other forms of apparatus.
While the form of mechanism herein shown and described constitutes a preferred form of embodiment of the invention, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
